Automatic control barrier

Automatic meter reading (AMR) is the technology of automatically collecting consumption, diagnostic, and status data from water meter or energy metering devices and transferring that data to a central database for billing, troubleshooting, and analyzing.\nThis technology mainly saves utility providers the expense of periodic trips to each physical location to read a meter.
Another advantage is that billing can be based on near real-time consumption rather than on estimates based on past or predicted consumption.
This timely information coupled with analysis can help both utility providers and customers better control the use and production of electric energy, gas usage, or water consumption.

In parallel computing, a barrier is a type of synchronization method.
A barrier for a group of threads or processes in the source code means any thread/process must stop at this point and cannot proceed until all other threads/processes reach this barrier.

A barrier certificate or barrier function is used to prove that a given region is forward invariant for a given ordinary differential equation or hybrid dynamical system.
That is, a barrier function can be used to show that if a solution starts in a given set, then it cannot leave that set.

A boom barrier, also known as a boom gate, is a bar, or pole pivoted to allow the boom to block vehicular or pedestrian access through a controlled point.
Typically, the tip of a boom gate rises in a vertical arc to a near vertical position.
Boom gates, especially manually operated ones, are often counterweighted, so the pole is easily tipped.
Boom gates are often paired either end to end, or offset appropriately to block traffic in both directions.
Some boom gates also have a second arm which hangs 300 to 400 mm below the upper arm when lowered, to increase approach visibility, and which hangs on links, so it lies flat with the main boom as the barrier is raised.
Some barriers also feature a pivot roughly half way, where as the barrier is raised, the outermost half remains horizontal, with the barrier resembling an upside-down L when raised.

Inventory control or stock control can be broadly defined as the activity of checking a shop's stock.
It is the process of ensuring that the right amount of supply is available within a business.
However, a more focused definition takes into account the more science-based, methodical practice of not only verifying a business's inventory but also maximising the amount of profit from the least amount of inventory investment without affecting customer satisfaction.
Other facets of inventory control include forecasting future demand, supply chain management, production control, financial flexibility, purchasing data, loss prevention and turnover, and customer satisfaction.

The Norway–Russia border barrier is an international border barrier built by Norway on the Norway–Russia border.
Construction of the barrier began in September 2016 and took a few months.
The intent of the project was to prevent the smuggling and illegal crossing of migrants from the Middle East, mainly from Syria, who have used Russia as a route of entry into Norway.

The Samson Remote Controlled Weapon Station (RCWS), also known as Katlanit (קטלנית in Hebrew: lethal is a Remote Weapon System that enables a variety of devices to be operated automatically or by remote control, including 5.56 mm, 7.62 mm, and 12.7 mm .50 BMG machine guns, 40 mm automatic grenade launchers, anti-tank missiles and observation pods.

A vapor barrier is any material used for damp proofing, typically a plastic or foil sheet, that resists diffusion of moisture through the wall, floor, ceiling, or roof assemblies of buildings and of packaging to prevent interstitial condensation.
Technically, many of these materials are only vapor retarders as they have varying degrees of permeability.
